How can the game company that developed the game is still standing when that kind of shir happened?
Like, the MC could sue them to oblivion, or barge to their office, and ask them to take responsibility by either revert it from their back end, or simply helping the MC to defeat the demon lord himself by maxing his levels + giving loads of OP equipments.
Also, the stuffs that they said about the game is also doesn't make any sense at all, like the inability to create another account for example (if you ever played any online game, you know that this is pure BS, and impossible to pull off).
This was my first thought, but no; M and S refer to the size of the avatar. It actually stands for Medium and Small. (Yes, this is a late reply. I'm making it anyway for posterity.)
